Sky Nectar was water which had passed through a type of fungus which grew at the top of Ironwood trees. The fungus made the water taste very sweet and delicious. Quint and Maris drank Sky Nectar after the Galerider crashed and they had climbed up an Ironwood tree for safety from the dangers of the ground of the Deepwoods in the book Clash of the Sky Galleons. It was possible to find Sky Nectar at the bottom of Ironwoods, but this was dangerous to drink as more other substances often got mixed in with it, so Quint and Maris climbed to the top of the tree and drank it with pine-kernels. Other names for Sky Nectar were Kobold's Tears, The Gift of Riverrise and Cloudtree Juice.
